WebThe trigger event for the extinction of C. megalodon seems to have been global cooling. To start, if C. megalodon had a warm blooded metabolism through gigantothermy, then it would need a higher calorie intake than … WebGIGANTOTHERMY Some scientists suggest that when animals become extremely large, entirely new processes come into play to maintain an internal body temperature. The argument for gigantothermy can be …
http://www.tuonindefu.com/?p=4691 WebGigantothermy was proposed as one way that dinosaurs kept warm without resorting to endothermic techniques. Paleontologist Robert Bakker (Dinosaur Heresies, 1986) protested against this using animals such as elephants as examples along with the idea that the longer it takes for an animal to cool down the longer it takes for it to warm up. So if ...
WebJan 1, 2024 · The evolution of endothermy in birds and mammals is regarded as one of the most important transitions in vertebrate evolution, providing an extraordinary case of evolutionary convergence between these groups that was pivotal to their widespread geographic distribution and ecological success ( 1 ). WebMay 15, 2013 · Gigantothermy is a combination of ectothermic homeothermy ( Spotila et al., 1973 ), the maintenance of a relatively high body temperature by vascular adjustments in tissue insulation ( Fig. 1 ), with inertial homeothermy resulting from large body mass ( McNab and Auffenberg, 1976 ).
WebGigantothermy, though, would not be enough to keep a leatherback warm in cold northern waters. It is not enough for whales, which supplement it with a thick layer of insulating blubber (fat). Leatherbacks do not have blubber, but they do have a reptilian equivalent: thick, oil-saturated skin, with a layer of fibrous, fatty tissue just beneath ...
